This is a tesseract mod I have spent a few months on, It incorporates Bullet physics, Angel Script, and a new script based dynamic entity system.
To see more follow the link. This is still in the pre pre pre alpha state, and is more at a conceptual point.

Alought most the info on Rival will be posted on the tesseract forums I just wanted to tell people who plan on developing on this game platform or what to play with this engine mod, that I am asking for feature requests (nothing too crazy). Anything you would like to see in the engine, either engine update, angel script functionality, editmode feature, etc.
